| 摘 要： | 研究了添加微量Sc，Zr的Al-Mg合金的再结晶行为，结果表明：Al-Mg-Sc-Zr合金的再结晶起始温度为400℃，细小、弥散基体共格的析出相对位错和亚昌的钉扎作用是合金再结晶温度大幅度提高的主要原因，再结晶形核机制为亚聚合机制。

| Abstract: | The recrystalization behavior of Al-Mg alloys with Sc and Zr additives was studied.It is found that the recrystallization of the alloy began at 400℃.The main reason of the great increase of recrystallization temperature is attributed to that the dislocations and subgrain boundaries.The recrystallizing nucleation mechanism was the subgrain boundary merging mechanism in the alloy are pinned by ultrafine dispersed coherent precipitates. |
